  • the present disclosure relates to a method to produce titanium master alloy for titanium- aluminum based metal alloys.
  • titanium alloys are produced from titanium "sponge", the product of a process known as the "Kroll Process”. In subsequent steps, aluminum and other alloying metals must be added to the sponge by using various melting processes. Therefore, the cost of titanium alloys is several times higher than the original cost of titanium. For example, in one 2015 publication, titanium production cost is indicated to be $9.00/kg (Ma Qian and Francis H. Froes, ed., Titanium Powder Metallurgy Science, Technology and Application (Elsevier Inc., 2015), p. 37)) whereas the cost of Ti-Al-V is $17.00/kg.

  • the methods provide a simple and more economical way to produce titanium-aluminum based alloys. With one or more embodiments of the instant disclosure, these methods do not require the addition of any soluble titanium (such as titanium chlorides) to the electrolyte, which thereby further reduces production cost. Also, the present disclosure provides for alloy products (e.g. Ti-Al master alloys) that are lightweight and "wool-like" or powdery products. As detailed in paragraph [0068] below, the temperature and composition of the electrolyte bath appears to influence the physical form of the titanium-aluminum master alloy formed on the cathode.
